You can extract music from any game directory if you have the right extracting program, I recently found one and extracted all the music from Half-Life 2, saving about a tenner on the soundtrack.
But there's nothing special about the music from SWBFII, at it's most interesting it's simply music from the movies, like Battle of the Heroes.
